Rampant fear or unquestioning enthusiasm. These seem to be the two fundamental attitudes people have about Generative AI models. Programs like Chat GPT, Bloom, and Replika are demonstrating the power, potential, and problems associated with having technology that seems to talk. Aside from getting some definitional clarity around what Chat/AI is and is not, I present here a couple of Use Cases. They may inspire in you, as they have in me, both fear and enthusiasm.
Let’s Call It What It Is: Simulated Talking
A few definitions might be in order. First of all, Artificial Intelligence (AI) is a large field, so let’s be clear that AI and Generative AI are different things. AI models are ones where you feed in data to get recommendations and predictions. We use simple models and algorithms ourselves, for instance, checking the weather by looking outside; that’s an unsophisticated algorithm that isn’t terribly predictive. In the past, computer models were similarly limited. They broke down fairly quickly if the variables got complicated or the model tried to look too far in the future. I can guess the weather in an hour, but what about next Sunday at 11 am, when I want to play pickleball? AI means that the models are big enough and full of enough data that the predictive accuracy is far beyond what computers “used” to predict. A self-driving car might be an example of AI. It’s not creating text or art, but it needs a huge influx of data and sophisticated decision-making capabilities in order to navigate a very complex environment.
Generative AI, which I’ll also call Chat/AI here, is a model that can create “new” content as part of its predictive output. You feed it tons of examples, and it creates something “new” or seems new, based on previous human-created patterns that made sense. The following example came from Prof. Louis Hyman, who will be discussed below. Suppose you asked Chat/AI to fill in the cat sat on the ____. The model might suggest floor, chair, lap, or mat. But mat might be the highest likelihood, perhaps 50%, so the generative AI picks that word.
